# How to close Data Probe when starting Slicer?

Dear experts,

I have a question , this option is always expanded every time I start Slicer.

In fact, I don’t use this option often, so I need to close it manually every time.

Is there a way to change the unexpanded state as the default.

Any scripts?

As is shown in this picture.

You can use the method `setDataProbeVisible`. See here for more details

as part of the application startup script
